Abstract: In this paper, we present performance improvement techniques for data retrieval from customized data warehouses for efficient querying and Online Analytical Processing (OLAP) in relation to efficient database and memory management. Different database management techniques, e.g. indexing, partitioning etc. play vital role in efficient memory management. A comparison of data retrieval time for a particular query from a relational database as well as data warehouse database with and without indexing is performed. We show that the application of different database management techniques result faster query execution by reducing data retrieval time. This improved efficiency may increase the efficiency of OLAP operations, which results better data warehouse performance.

Keywords - Data Warehouse, Indexing, OLAP, Partitioning, Querying.

Abstract: Handling missing attribute values is the greatest challenging process in data analysis. There are so many approaches that can be adopted to handle the missing attributes. In this paper, a comparative analysis is made of an incomplete dataset for future prediction using rough set approach and random tree generation in data mining. The result of simple classification technique (using random tree classifier) is compared with the result of rough set attribute reduction performed based on Rule induction and decision tree. WEKA (Waikato Environment for Knowledge Analysis), a Data Mining tool and ROSE2 (Rough Set Data Explorer), a Rough Set approach tool have been used for the experiment. The result of the experiment shows that the random tree classification algorithm gives promising results with utmost accuracy and produces best decision rule using decision tree for the original incomplete data or with the missing attribute values (i.e. missing attributes are simply ignored). Whereas in rough set approach, the missing attribute values are filled with the most common values of that attribute domain. This paper brings out a conclusion that the missing data simply ignored yields best decision than filling some data in the place of missing attribute value.

Country : India
Authors : S.Valarmathi, Mr.S.Sathishkumar
: 10.9790/0661-0931115      logo

Abstract: A resilient execution environment can be developed for a critical application even in the presence of corrupted OS kernel. The attacker tries to capture the application content by corrupting the OS when an application is executing. In previous case the attacker corrupts the OS by injecting code then the application terminates immediately without executing it. In this current system even in the presence of corruption the application is executed with out any interception and it provide a resilient authenticated execution of critical application in entrusted environment by using Virtual Machine Monitor (VMM). VMM is a monitoring technique to monitor all the activities during execution and it is one of the online based recovery schemes to identify any such corruption. It repairs the memory corruption and allows the process for normal execution. VMM solutions generally broadcast into two categories they are memory authentication and memory duplication. Memory authentication is to check the integrity of an application and memory duplication is to rectify the corruption. The proposed system is applied for military application, hospitals, and colleges and for all critical applications. Keywords- Memory corruption, operating systems, security, Virtual machine monitors (VMM).

Title : A Novel Approach for Event Monitoring In Wsn Using Sleep Scheduling
Country : India
Authors : K.Ramya, Mr. V.Senthil Murugan

Abstract: A broadcasting delay is an important problem for the application of the critical event monitoring in wireless sensor networks. To prolong the network lifetime some of the sleep scheduling methods are always employed in WSNs it results in a significant broadcasting delay. A novel sleep scheduling method to be proposed it is based on the level-by-level offset schedule to achieve a low broadcasting delay in wireless sensor networks (WSNs). There are two phases to set the alarm broadcasting first one is, if a node detects a critical event, it create an alarm message and quickly transmits it to a center node along a pre-determined path with a node-by-node offset way. Then the center node broadcasts the alarm message to the other nodes along another predetermined path without collision. To eliminate the collision in broadcasting, a colored connected dominant set (CCDS) in the WSN via the IMC algorithm is established. An on demand distance vector routing protocol is established in one of the traffic direction for alarm transmission. The proposed system is used in military and forest fire application.

Title : Mouse Activity by Facial Expressions Using Ensemble Method
Country : India
Authors : Anandhi.P, Gayathri.V

Abstract: This graduation project aims to present an application that is able of replacing the traditional mouse with the human face as a new way to interact with the computer. Human activity recognition has become an important application area for pattern recognition. Here we focus on design of vision-based perceptual user interfaces. The concept of the second order change detection is implemented which sets the base for designing complete face-operated control systems ,where the mouse is replaced by 'nose' as pointer and 'blinking eyes' for clicking option. To select a robust facial feature, we use the pattern recognition paradigm of treating features. Using a support vector machine (SVM) classifier and person-independent (leave-one person-out) training, we obtain an average precision of 76.1 percent and recall of 70.5 percent over all classes and participants. The work demonstrates the promise of eye based activity recognition (EAR) and opens up discussion on the wider applicability of EAR to other activities that are difficult, or even impossible, to detect using common sensing modalities. The visual based human computer interaction is probably the most widespread area in HCI research. Different aspects of human responses can be recognized as a visual signal. One of the main research areas in this section is through Facial Expression Analysis and Gaze Detection (Eyes Movement Tracking).

Keywords—Ubiquitous computing, feature evaluation and selection, pattern analysis, signal processing.

Abstract: The whole finance of the world revolves around currency. It may be physical or digital. Currency functions as a unit of account providing a common measure of goods and services being exchanged. The enormous use of paper currency has resulted in deforestation, which is leading to ecological imbalance. For conserving the space, time, and environment there is a need for an alternative currency. In this paper, ubiquitous virtual money is proposed, which is accessible throughout the environment. Ubiquitous currency is a form of electronic money that is spent like pocket change. The transactions can be made secure by the use of biometric identifiers.

Title : Comprehensive Evaluation of AODV, DSR, GRP, OLSR and TORA Routing Protocols with varying number of nodes and traffic applications over MANETs
Country : India
Authors : Gagangeet Singh Aujla, Sandeep Singh Kang

Abstract: Wireless Technology is at its peak when we talk about research and innovation. This field has become a hub of invention of new theories and structures. Mobile Ad-hoc Network is a special point of focus for the researchers. MANET is a collection of wireless mobile nodes which forms a dynamic temporary network without using any existing infrastructure. In recent time the market of mobile devices, laptops, hand held and portable devices is at its zenith so communication between such devices is an important issue. Routing is an essential part in the success of communication among these mobile structures. Routing protocols play an important role for finding an efficient and reliable route from source to destination. In the literature, there are numerous MANET routing protocols aiming to find the most suitable path from source to destination. In this paper, a comprehensive simulation based performance study and analysis is performed on various types of routing protocols over MANET. Ad Hoc On-Demand Distance Vector (AODV), Dynamic Source Routing (DSR), Temporally-Ordered Routing Algorithm (TORA), Optimized Link State Routing (OLSR) and Geographic Routing Protocol (GRP) has been considered for investigation in this paper based on OPNET simulation. Moreover the performance of these routing protocols will be measured on the basis of throughput, delay, load and data dropped metrics

Title : An automatic Text Summarization using feature terms for relevance measure
Country : India
Authors : Anita.R.Kulkarni, Dr Mrs. S.S.Apte

Abstract: Text Summarization is the process of generating a short summary for the document that contains the overall meaning. This paper explains the extractive technique of summarization which consists of selecting important sentences from the document and concatenating them into a short summary. This work presents a method for identifying some feature terms of sentences and calculates their ranks. The relevance measure of sentences is determined based on their ranks. It then uses a combination of Statistical and Linguistic methods to identify semantically important sentences for summary creations. Performance evaluation is done by comparing their summarization outputs with manual summaries generated by three independent human evaluators.

Keywords: - Generic text summarization, Relevance measure, Semantic Analysis, Term-frequency Rank.

Title : Enhanced Adaptively Space-Time-View Error Concealment for 3D Multi-View Video Transmission over Noisy Channels
Country : Egypt
Authors : Walid El-Shafai

Abstract: Decoding of 3D multi-view video coded bit-streams that are transmitted over noisy channels can suffer from error propagation in the space, time and view domains. To improve the quality of reconstructed 3D video, we propose adaptive Error Concealment (EC) algorithms to conceal the erroneous blocks of intra-coded and inter-coded frames. Our proposed algorithms adapt to the motion characteristics of the 3D video and to the error patterns. We propose three adaptive EC algorithms for intra-frames, which are Adaptive Time Domain Error Concealment (ATDEC), Adaptive Space Domain Error Concealment (ASDEC) and a hybrid Adaptive Space-Time Domain Error Concealment (ASTDEC). We also propose three adaptive EC algorithms for inter-frames, which are Adaptive Inter-View Domain Error Concealment (AIVDEC), Adaptive Time Domain Error Concealment (ATDEC) and joint Adaptive Time and Inter-View Domain Error Concealment (ATIVDEC). Our simulation results show that the proposed adaptive EC algorithms can significantly improve the objective and subjective 3D video quality transmitted over noisy channels.

Country : India
Authors : Shilpa Jaiswal, Anil Kumar Patidar

Abstract: Ad hoc networks have been used in many applications which mandate a dynamic setup in the absence of fixed infrastructure. The design of ad hoc network has been mainly focuses on proper operation. It is possible that eventually a malicious node becomes easy to deploy in ad hoc n/w and they cause among other impact performance degradation. One attack that can deploy by malicious node is black hole attack. This paper reviews the problem of occurrence of black hole attack and its solution technique proposed enhancement in proactive routing protocol Destination Sequenced Distance Vector Routing protocol Using trust based and hop count method. Keywords: ad hoc networks, black hole, security, routing, DSDV.
